Storm slabs remain reactive to human triggers, especially in wind affected terrain.
Continue to make conservative terrain choices while the storm snow settles and stabilizes.
Triggering deeper weak layers is most likely to occur in isolated alpine areas where a supportive crust below the recent snow is not present.
Up to 70 cm of recent snow and strong west winds have formed fresh storm slabs that will be most reactive in wind affected terrain.
On Wednesday, several explosive triggered storm slab avalanches up to size 2 were reported on north and easterly aspects in the alpine.
45-70 cm of recent snow and strong west winds have formed slabs overlying a thick crust.
Above 1800 m, a crust is buried 50 to 100 cm deep. Beneath it, the snowpack contains several additional crusts, and in some locations, a weak, sugary facet layer near the ground.
Below 1800 m, the mid/lower snowpack is moist to ground in most areas.
